Tomographic reconstruction

Look at other dictionaries:

  • Tomographic reconstruction — The mathematical basis for tomographic imaging was laid down by Johann Radon. It is applied in Computed Tomography to obtain cross sectional images of patients. This article applies in general to tomographic reconstruction for all kinds of… …   Wikipedia

  • Reconstruction algorithm — In tomography, a variety of practical reconstruction algorithms have been developed to implement the process of reconstruction of a 3 dimensional object from its projections. These algorithms are designed largely based on the mathematics of the… …   Wikipedia

  • Iterative reconstruction — is a method or group of algorithms used to reconstruct 2D and 3D images from the projections of an object. The technique differs greatly from the more ubiquitous filtered back projection (FBP) method. In X ray computed tomography, this method is… …   Wikipedia

  • Software tools for molecular microscopy — There are a large number of software tools or software applications that have been specifically developed for the field sometimes referred to as molecular microscopy or cryo electron microscopy or cryoEM. Several special issues of the Journal of… …   Wikipedia

  • Computed tomography — tomos (slice) and graphein (to write).Computed tomography was originally known as the EMI scan as it was developed at a research branch of EMI, a company best known today for its music and recording business. It was later known as computed axial… …   Wikipedia

  • Tomography — Basic principle of tomography: superposition free tomographic cross sections S1 and S2 compared with the projected image P Tomography refers to imaging by sections or sectioning, through the use of any kind of penetrating wave. A device used in… …   Wikipedia

  • X-ray computed tomography — For non medical computed tomography, see Industrial CT Scanning. catSCAN redirects here. For the Transformers character, see Transformers: Universe. X ray computed tomography Intervention A patient is receiving a CT scan for cancer. Outsid …   Wikipedia

  • Single photon emission computed tomography — (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. It is very similar to conventional nuclear medicine planar imaging using a gamma camera. However, it is able to provide true 3D information.… …   Wikipedia

  • William H. Oldendorf — William Henry Oldendorf (1925 December 14, 1992) was an American neurologist, physician, researcher, medical pioneer, founding member of the American Society for Neuroimaging (ASN), and originator of the technique of Computed Tomography. Early… …   Wikipedia

  • radiation — radiational, adj. /ray dee ay sheuhn/, n. 1. Physics. a. the process in which energy is emitted as particles or waves. b. the complete process in which energy is emitted by one body, transmitted through an intervening medium or space, and… …   Universalium

  • Radon transform — In mathematics, the Radon transform in two dimensions, named after the Austrian mathmematician Johann Radon, is the integral transform consisting of the integral of a function over straight lines. The inverse of the Radon transform is used to… …   Wikipedia
